CASE FOR INCANDESOENT-ELECTRIC LAMP SOCKETS.

Specification of Letters Patent.

Application filed January 16, 1911. Serial No. 602,762.

a To all whom it concern:

, Be it known that we, AUGUST WEBER, Sr, each a citizen of. the

and Jonu WEBER,

I residing at Schenectady, county of Schenectady, and State of New York, have invented certain new and useful improvements in Cases for Incandescent- Elw-tlfic-Iamp Sockets, of which the followi is a specification.

he. invention relates to such improveand consists of the novel construction and combination of parts hereinafter deand subsequently claimed.

' ,Beference may behad to' theaccompanyin Fig. 3. Fig. 6

ing drawings, and the reference. characters marked thereon,which form a part of this specification.

Similar characters refer to similar parts in the several figures therein.

Fig. 2 is a. central vertical section of. the same taken on the broken line 2-2 inFig. 1.' Fig. 3 is a view inside elevation of a case for'an incandescent electric.

Fig. .8 is a'to'p plan view of the shell of the same with the cap removed. wFig. the capof the same. Fig. 10 is a View in side elevation of a broken-away portion of the cap.

The principal object ofthe invention is to facilitate the locking together of the cap andsleeve members of the case for an incandescent electric lamp-socketin numerous positions of relative rotative adjustment,

Other ob'ects will appeanin connect-ion with the following description.

In carrying out our invention, we rovide the case-members with means where y they we adapted to interlock against ajongitudr t) is a'bottom plan view of case', the sleeve being provided with the usualkey-slot 3. The cap' is adapted to telescopically receive and fit the inner end of the sleeve, and-the sleeve has near its inner catches, 4, which known manner, preferably by transversely slitting the wall of the sleeve, anddisplacing outwardly a portion of the sleeve-wall on the inner side of said slit. The catches, 4, are adapted to enter and interloc with an annularly grooved vof the cap, as shown in. Fig. 2. The catches, 4, are preferably inclined or beveled as shown, so;that such interlocking is accomplished by the telescopic application of the capto the sleeve. The grooved portion, 5, of the cap-flange preferably extends throughout the circumferential extent of thus adapted to interlock in any or substantially any relative rotative position; and, in

permitted a. relative rotative movement. The sleeve is with numerous equidistant rectangular apertures, 6; and the flange of the cap is provided with a plurality of inward projections, 7, each adapted, to enter the several apertures,6, when brought opposite thereto. Each of the projections, 7, is preferably the metal between said slits, thereby causing the cut-metai edges of the to engage the cut-metal walls of an aperture, 6, to resist relative rotary movement.

ings,-.1, is the sleeve and, 2, the cap of the portion, 5, of t 1e flange the flange, so that the'cap and sleeve are.

formed ,by making two vertical slits in the flange of the cap, and inwardly displacing displaced portion Referring to Figs. 3, 4 and 5 the means Patented July 8, 1913.

end .a plurality of outward projections or may be formed in anythe absence of preventive means, would he provided near its inner end 'construction shown in Figs. 3, 4 and 5,

whether the case be for a key or a keyless socket. In the construction shown in Figs. 1 and 2, a single projection, 7, will usually be found sufficient, except in a case for a key-socket where the width of the key-slot, 3, may occupy more than the space of one of the apertures, 6, in which'case two or more projections, 7, may be employed. We prefer, however, to employ two or more projections, 7 or 17, in the respective construe tions shown.

In either form of our invention shown, the cap and sleeve can be'telescopically applied one to the other. and interlocked against a longitudinal movement of separation in any relative rotary position, whether the projection, 7 or 17, on the one member is in perfect alinement with the respective aperture, 6 M16, in the other member, or

not, a very slight relative rotative movement only being necessary to seat the projection in the aperture after the parts are interlocked, should itnot be seated therein during the interlocking operation. Such relative rotary movement as would be necessary in any case to thus seat the projection in the aperture would be so slight as to be ne ligible in the operation and use of the soe ket. The cap and sleeve can'therefore by means of this invention be interlocked and secured against relative rotary movement in substantially any relative rotary position in which they may be applied to each other.

For certain purposes of the invention the lugs or catches, 4, may be formed in any known manner, whereby they are adapted to interlockwith the grooved portion of the cap-flange; and the lugs or projections, 7 or 17, may be formed in any known manner whereby they are adapted to enter the respective apertures, 6 or 16, and prevent relative rotary movement of the parts.

Referring to the construction shown in Figs. 7 to 10, inclusive, the cap is provided with one or more projections, 18, on the annular offset portion, 19, of the cap, adapted to enter the several seats, 20, formed in the upper edge of the shell, said projections and seats being in such number and location that. one or more projections, 18, will automatr cally enter one or more, respectively, of said seats when the shell and cap are applied telescopically to each other in any relative rotativeposltion. This is made possible by forming said seats b serrating certain portions of the upper e ge of the shell, whereby a plurality of seats or openings are formed adjacent to one another, and separated from one another by a V-shaped tooth or projection on the upper edge of the shell.

In the preferred form of cap shown, the annular groove, 5, is formed by pressing out a portion of the flange of the cap to form a continuous annular shoulder seat or ledge in a plane perpendicular to the axis of the case, adapted to interlock with the lugs or catches on the sleeve; and this groove is formed along the middle portion of, the flange on the cap, leaving, on both the innor and outer sides of the groove, cylindrical portions of the flange adapted to telescopically fit the sleeve.

No claim is made herein to the specific forms of the invention employing a notched or serrated edge on one of the parts as a means for preventing relative rotation, as these features of the invention are articularly claimed in our co-pending app 'cation Serial No. 501,776, filed June 12, 1909.
